Tina’s Mouth: An Existential Comic Diary is the story of 15-year-old Tina M., an Indian-American girl attending a posh private high school in California, and, like so many her age, trying to find her place in the world. A natural for self-reflection, Tina’s ripe for existentialism when her hippie English teacher introduces the subject to the class. The assignment for the year is for each student to find “true and authentic meaning and purpose” in their existence. What follows is Tina’s project. As the subtitle suggests, her search is in the form of an existential comic diary.
